BALE-BAND TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 231,273, dated August17, 1880.

(No model.)

To all whom it may concern:

Be it known that I, CHARLES T. CHRIST- MAS, ot'Riverton, in the countyof Bolivar and State of Mississippi, have invented a new and usefulImprovement in Bale-Band Tigh teners, of which the following is aspecification.

The invention relates to that class of devices known to the public asbale-band tighteners.

The construction and operation will be more particularly explainedhereinafter, with reference to the accompanying drawings, wherein Figure1 is a side elevation, and Fig. 2 an edge View, of myimprovedband-tightener.

Similar letters of reference indicate corresponding parts.

A is a lever of suitable length, and formed with the end a bent incurved form. B is a curved arm, hung on lever A, near the bent endthereof, by a pin, 1), which permits the arm to swing freely. Upon theouter end of arm B, at one side, is fitted a slotted block, 0, which isattached by a screw-pin or rivet, so that the block may turn on the arm.In a recess of the block 0 is hung a cam-lever, d, in a position forbeing turned to bear upon a band that may be placed in the slot of block0. Upon the side of lever A, near the end, is attached a similar block,6, also slotted and fitted with a cam-lever, f. At the extreme end oflever A is fitted a friction-roller, g.

In using the tightener the band is placed around the compressed bale,and one end (the button end when the ordinary button-band is used) isplaced in the slot of block a on arm B and clamped by lever d. The otherend of the band is securedin the block 6 of lever A; then by pressingdown the outer end of lever A the two ends will be brought together andheld by one hand of the operator on the lever while the ends of the tieare being secured with the other hand. The tightener may be thenremoved.

The roller g permits the end of the lever to slide over the bale readilywithout catching.

By this tightener each band may be drawn tightly to the compressed baleand all the bands drawn to an equal tension, so that there will be butslight expansion of the bale when removed from the press, and thepressure on the bands will be equally distributed.

Having thus described my invention, I claim as new and desire to secureby Letters Pateut- Abale-band tightener consisting of two endcurved andcross-pivoted bars, A B, having on corresponding sides of the ends aswiveled slotted block and cam-lever, as shown and described.
